lwaste paper of that class which is intended to be reconverted into new paper by the paf per mills; to so construct the apparatus which I employ for this purpose as to 4insure the rapid and effective separation of dustand loose dirt from the aperand to produce other improvements t e details of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanyingdrawings, in which- Figure 1 is a side view of my improved mechanism showing the same in position for use and for convenience in illustration 'show- 'ing the supporting floor in section,Fig. 2isa plan view of the same, and, Fig. 3 is a sectional view on line xof Fig. 1.

Similar numerals refer4 to similar parts throughout the several views.

In carrying out my invention, I employ a suitable framework whichis ada ted to be supported upon the floor of abuil ing such as 1s indicated at 1, saidl framework comprising front standards 2 and 3 and longer lrear standards 4 and '5-the front standards being connected by a horizontal frame bar 6 and the rear standardssimilarly connected by across bar 7 which is indicated in dotted lines in Fig. 1 of the drawing. j

8 represents a shaft which is journaled in the cross bar 6 and in a standard 2,

9 represents a shaft which is parallel with i the shaft 8 and which also has its end bearings in the frame cross ieee 6 and a standard corresponding wit the standard a2. Each of the shafts 8 and 9 carries adjacent to the cross bar 6 awheel10,thesewheels be! ing anged on their forward sides asindi cated at 10, after the manner of car wheels. 10b re resent wheels which correspond in form an size with the wheels 1() one of these wheels being pivoted to the cross frame piece 7 at a point opposite and above each of the wheels 10. l

11 represents a cylinder, the body of which is formed of screen wire and which at each end has a terminal band `or ring 11". forward end of the cylinder is provided with a flaring unperforated extension 11b. The inner surface of the cylinder is provided at intervals throughout itslength, with fixed parallel bars such as are indic'ated at 12.

he cylinder thus formed is, as shown', su

` portedA above and upon the peripheries of t e wheels 10 and 10b, the flanges of said wheels engaging the forward sides`of the end bands or rings 11 of .the cylinder. yUpon the shaft 8 is vcarried a small sprocket wheel 13 which is .connected with a similar sprocket wheel 14 upon the shaft 9 through the medium of an endless chain 15. The shaft 8 also carries a s rocket wheel 16 which through an endless c ain 17 isconnected with a sprocket wheel 18 carried on a line shaft 19 which may be supported in hangers or by other suitable means from the underside of the floor 1. This `shaft 19'carries a belt wheel 20 overv which a belt may run from a suitable source of power.

J ournaled between and slightly in front of the upper end portions of the rear standards 4, is a roller 21 over which runs an endless -conveyer belt or apron 22, the latter running rearward and downward from the rear end of the cylinder 11 through an openin 1a in thev Hoor and thence to and about a rolfler 23, the central shaft of which is rotatably mounted in fixed hangers 24. This oller shaft which is indicated at 23a also carries a sprocket wheel 25 over which runs an endless chain belt 26, said belt also running over and engaging the teeth of a sprocket wheel 27 which is carried on a shaft 28, the latter being journaled in a hanger 29. U on the shaft 28 on the inner side of the 'sproc et wheel is carried a beveled gear wheel indicated in dotted lines in Fig. 2 of Athe drawing at 30, the teeth of this bevel gear wheel meshing with those of a second'bevel gear wheel 31 which is carried by the shaft 19.

In the construction of the endless apron or conveyer belt 22, I form the body of the same of a flexible material, the outer surface of The which has secured thereto at intervals cross rection of the length of the s aft 19, an endless apron or carrier 35, the latter also pass" ing about a roller 36 corresponding with the ro ler 34 which is suitably j ournaled in frame standards 37 which rise from the hoor .,1 at opposite points and at a suitable distance to one side of the forwardend of the cylinder 1 1. Upon the inner end of the shaft of the roller '36, is carried a sprocket Wheel 38 which is connected by means of a sprocket chain 39 (see Fig. 3) with a sprocket wheel 40 partly indicated in Fig. 1 of the drawing,'which is .carried u on the outer end of the shaft 8.

The stan ard 33 is connected with the corresponding standard 37 by a horizontal side board 41 while a similar side board 42 connects the standards 2 and 3y with the remain ing standard 37.

t will be understood that rotary motion being im arted to the shaft 19 through a belt on the W eel 20, such motion will be ltransmitted to the shaft 8 through the chain 17 and through the chain 15 to the shaft 9. The rotary motion thus imparted to the cylinder supporting wheels 10 ,results in a rotary motion of the c linder 11 in the opposite direction. It willbe understood that through. the gear connections heretofore described, rotary motion will also be transmitted to the roher 23 resulting in a travelin motion of the conveyer belt 22 about the ro ers 23 and 21 in the direction of the arrow indicated inv imparted tothe parts as hereinbefore de-l scrlbed, the waste paper to be cleaned is suitably fed on to the u yper `side of. the conve er 22 and carried thereby u ward over the ro ler 21 and into therear en of the cylinder 11; The paper which is thus discharged into the cylinder 11 is bythe rotation of the latter and by engagement with the internal bars 12 v shaken or agitated sufficiently to cause the loose dust particles clinging to the pieces of paper or particles of dirt whichare readily detachable from the paper, to fall therefrom through the openings in the tubular screen which forms the cylinder, while the aper is gradually fed to and through the orward end of the cylinder through the inclination of the latter on to the traveling apron 35. TheV vtraveling motion of this apron is comparatively slow and while the paper is being carried to the discharge end of the apron, certain grades of the paper are removed by hand from the apron 35 and arranged in separate receptacles, while the remaining and less ing the separation of the paperinto-various grades after cleaning.

What I claim, is:

l In a device of the character described, the 'combination with spaced )airs of standards, of hanged wheels mounted upon said stand ards, the hanged wheels of one pair of standards being inclined with relation to said standards, a 'air of stub shafts upon which. the hanged W ieels of the other pair of standards are mounted, a chain and sprocket connection between said shafts, a screen comprising a wire mesh body portion, and annuar `ringsat the. opposite ends thereof, said rings resting u )on said hanged wheels, the inclined hange wheels being located above the other of said hanged wheels to thereby support said screen in an inclined position, a

line shaft, a support for said standards be-y neath which sald line shaft is located, a conveyer which passes through said lsu ort and serves to convey material tothe hlg est end of said screen, connections between said conveyer and the line shaft whereby said conveyer may be driven from the line shaft, a

connection between the line shaft and one of the stub shafts',4 a conveyer adapted to receive material from the discharge end of the screen, and a connection between one of said stub shafts and said conveyer. v

In testimony whereof I ahix 'my signature in presence of two witnesses. VALENTINE P. SCHMIDT. Witnesses:
